We conducted iTRAQ analyses using soluble proteins extracted from roots of non-transformant rice (NT) and previously generated HRZ-knockdown (HRZi) lines (Kobayashi et al., 2013 Nat Commun 4: 2792) cultivated under Fe-sufficient and Fe-deficient conditions. We identified and quantified 3,033 and 3,525 proteins in replicate 1 and 2, respectively, which totaled 4,884 proteins including 1,698 overlapping proteins between the two replicate experiments.
